supplements
Konjac glucomannan (KGM), also just called ‘glucomannan’, is a dietary fiber hydro colloidal polysaccharide isolated from the tubers of Amorphophallus konjac. It is used as a food, a food additive, as well as a dietary supplement in many countries. KGM is claimed to reduce the levels of glucose, cholesterol, triglycerides, and blood pressure.
The objective of this study was to evaluate the effect of the consumption of gummy candy enriched with KGM on appetite and to evaluate anthropometric data, biochemical, and oxidative stress markers in overweight individuals. Forty-two participants aged 18 to 45 years completed this randomized, double-blind, placebo-controlled clinical trial. Participants were randomly assigned to consume for 14 days, 2 candies per day, containing 250 mg of KGM or identical-looking placebo candy with 250 mg of flaxseed meal, shortly after breakfast and dinner. As a result, we observed that there was a reduction in waist circumference and in the intensity of hunger of the participants who consumed KGM. The authors believe that a longer consumption time as well as an increased dose of KGM would contribute to even more satisfactory body results.
These findings seem promising, yet somehow I am not convinced. The study was small and short-term; moreover, the authors seem uncritical and, instead of a conclusion, they offer speculations.
Our own review of 2014 included 9 clinical studies. There was a variation in the reporting quality of the included RCTs. A meta-analysis (random effect model) of 8 RCTs revealed no significant difference in weight loss between glucomannan and placebo (mean difference [MD]: -0.22 kg; 95% confidence interval [CI], -0.62, 0.19; I(2) = 65%). Adverse events included abdominal discomfort, diarrhea, and constipation. We concluded that the evidence from available RCTs does not show that glucomannan intake generates statistically significant weight loss. Future trials should be more rigorous and better reported.
Rigorous trials are required to change my mind, and I am not sure that the new study falls into this category.
Drip IV is “Australia’s first and leading mobile healthcare company specialising in assisting with nutritional deficiencies”. They claim to provide a mobile IV service that is prescribed and tailored individually to your nutritional needs. Treatment plans and customised infusions are determined by a medical team to suit individual requirements. They deliver vitamins, minerals and amino acids directly to the body via the bloodstream, a method they state allows for optimal bioavailability.
These claims are a little puzzling to me, not least because vitamins, minerals and amino acids tailored individually to the nutritional needs of the vast majority of people would mean administering nothing at all. But I guess that virtually every person who consults the service will get an infusion [and pay dearly for it].
The Australian Therapeutic Goods Administration (TGA) seems to have a similarly dim view on Drip IV. The TGA has just issued 20 infringement notices totalling $159,840 to the company and to one of its executive officers. The reason: unlawful advertising of intravenous infusion products to Australian consumers on a company website and social media. Ten notices totalling $133,200 were issued to the company and ten notices totalling $26,640 were issued to an executive officer. The TGA considers the intravenous infusion products to be therapeutic goods because of the claims made about them, and the advertising to be unlawful because the advertisements allegedly:
- contained prohibited representations, such as claims regarding cancer.
- contained restricted representations such as that the products would alleviate fatigue caused by COVID-19, assist in the treatment of Graves’ Disease and Alzheimer’s Disease, and support the treatment of autoimmune diseases such as Multiple Sclerosis. No TGA approval had been given to make such claims.
- referred to ingredients that are prescription only, such as glutathione. Prescription medicines cannot be advertised directly to the public in Australia.
- contained a statement or picture suggesting or implying the products were ‘TGA Approved’. Advertising of therapeutic goods cannot include a government endorsement.
- contained a statement or picture expressing that the goods were ‘miraculous’.
Vitamin infusions have become very popular around the globe. There are now thousands of clinics offering this service, and many of them advertise aggressively with claims that are questionable. Here is just one example from the UK:
Modern life is hectic. If you are looking to boost your wellbeing, increase your energy levels, lift your mood and hydrate your body, Vitamin IV Infusions are ideal. Favoured by celebrities such as Madonna, Simon Cowell and Rihanna, Vitamin IV Infusions are an easy, effective way of delivering vitamins, minerals and amino acids directly into your bloodstream via an IV (intravenous) drip. Vitamins are essential for normal growth and staying healthy – but our bodies can’t produce all of the nutrients we need to function and thrive. That’s why more than one in three people take daily vitamin supplements – often without realising that only 15% of the active nutrients consumed orally actually find their way into their bloodstream. With Vitamin IV Infusions, the nutrients enter your bloodstream directly and immediately, and are delivered straight to your cells. We offer four different Vitamin IV Infusions, so you can choose the best combination for your personal needs, while boosting your general health, energy and wellbeing.
My advice to consumers is a little different and considerably less costly:
- to ensure you get enough vitamins, minerals, and amino acids, eat a balanced diet;
- to boost your well-being, sit down and calculate the savings you made by NOT using such a service;
- to increase your energy levels, take a nap;
- to lift your mood, recount the money you saved and think of what nice things you might buy with it;
- to hydrate your body drink a glass of water.
Perhaps it is time the authorities in all countries had a look at what these clinics are offering and what health claims they are making. Perhaps it is time they act as the TGA just did.
The UK medical doctor, Sarah Myhill, has a website where she tells us:
Everyone should follow the general approach to maintaining and restoring good health, which involves eating a paleo ketogenic diet, taking a basic package of nutritional supplements, ensuring a good night’s sleep on a regular basis and getting the right balance between work, exercise and rest. Because we live in an increasingly polluted world, we should probably all be doing some sort of detox regime.
She also happens to sell dietary supplements of all kinds which must surely be handy for all who want to follow her advice. Dr. Myhill boosted her income even further by putting false claims about Covid-19 treatments online. And that got her banned from practicing for nine months after a medical tribunal.
She posted videos and articles advocating taking vitamins and other substances in high doses, without evidence they worked. The General Medical Council (GMC) found her recommendations “undermined public health” and found some of her recommendations had the potential to cause “serious harm” and “potentially fatal toxicity”. The tribunal was told she uploaded a series of videos and articles between March and May 2020, describing substances as “safe nutritional interventions” which she said meant vaccinations were “rendered irrelevant”. But the substances she promoted were not universally safe and have potentially serious health risks associated with them, the panel was told. The tribunal found Dr. Myhill “does not practice evidence-based medicine and may encourage false reassurance in her patients who may believe that they will not catch Covid-19 or other infections if they follow her advice”.
Dr. Myhill previously had a year-long ban lifted after a General Medical Council investigation into her claims of being a “pioneer” in the treatment of chronic fatigue syndrome. In fact, the hearing was told there had been 30 previous GMC investigations into Dr. Myhill, but none had resulted in findings of misconduct.
Dr. Myhill is also a vocal critic of the PACE trial and biopsychosocial model of ME/CFS. Dr. Myhill’s GMC complaint regarding a number of PACE trial authors was first rejected without investigation by the GMC, after Dr. Myhill appealed the GMC stated they would reconsider. Dr. Myhill’s action against the GMC for failing to provide reasoning for not investigating the PACE trial authors is still continuing and began a number of months before the most recent GMC instigation of her practice started.
The recent tribunal concluded: “Given the circumstances of this case, it is necessary to protect members of the public and in the public interest to make an order suspending Dr. Myhill’s registration with immediate effect, to uphold and maintain professional standards and maintain public confidence in the profession.”
Chronic kidney disease is common, often progressive, and difficult to treat or prevent. Effective interventions would therefore be more than welcome. This paper explored the relation of habitual fish oil use with the risk of chronic kidney diseases (CKD).
A total of 408,023 participants (54.2% female) without prior CKD and with completed information regarding their consumption of major food groups and fish oil in the UK Biobank were enrolled. Fish oil use and dietary intakes were assessed by touch screen questionnaire and food frequency questionnaire, respectively. Incident CKD was recorded from hospital inpatient records.
At baseline, 128,843 (31.6%) participants reported taking fish oil supplements. During a median follow-up period of 12.0 years, a total of 10,782 (2.6%) participants developed CKD. With adjustments for important confounders, habitual fish oil use was associated with a significantly lower hazard of incident CKD (hazard ratio [HR], 0.90; 95% confidence interval [CI], 0.87-0.95), compared with non-use. Consistently, participants reporting ≥2 servings/week of oily fish (HR, 0.86; 95% CI, 0.79-0.94) and nonoily fish (HR, 0.86; 95% CI, 0.77-0.97) consumption had a lower hazard of incident CKD compared to those reporting no consumption ever. Additionally, among the 97,914 participants with data on plasma fatty acid, there were significant inverse relationships of plasma omega-3 polyunsaturated fatty acid (PUFA) (per SD increment, HR, 0.89, 95% CI, 0.84-0.94) and eicosatetraenoic acid (per SD increment, HR, 0.91, 95% CI, 0.87-0.96) with incident CKD.
The authors concluded that habitual fish oil use was associated with a lower hazard of CKD, which was further confirmed by the consistent inverse relations between fish consumption and circulating omega-3 PUFA concentration with incident CKD.
I like this paper! It shows in an exemplary fashion how to interpret an association between two variables: fish oil consumption does not necessarily CAUSE the lower risk, it is merely associated with it and there might be a number of non-causal explanations for the link. Whether there is a true cause-effect relationship needs to be investigated in further, differently designed studies. The present paper does not overstate its conclusions but it is nevertheless important, as it hopefully will prompt others to clarify the crucial issue of causality.
Wouldn’t it be nice, if researchers of so-called alternative medicine (SCAM) finally learned this simple lesson?
The impact of drug-induced liver injury (DILI) on patients with chronic liver disease (CLD) is unclear. There are few reports comparing DILI in CLD and non-CLD patients. In this study, the researchers aimed to determine the incidence and outcomes of DILI in patients with and without CLD.
They collected data on eligible individuals with suspected DILI between 2018 and 2020 who were evaluated systematically for other etiologies, causes, and the severity of DILI. They compared the causative agents, clinical features, and outcomes of DILI among subjects with and without CLD who were enrolled in the Thai Association for the Study of the Liver DILI registry. Subjects with definite, or highly likely DILI were included in the analysis.
The researchers evaluated the causal relationship between the clinical pattern of liver injury and the suspected drugs or SCAM products with the Roussel Uclaf Causality Assessment Method (RUCAM) system. RUCAM is a validated and established tool to quantitatively assess causality in cases of suspected DILI and/or SCAM product-induced liver injury. They also used the Clinical Assessment of Causality Scale to assess the association as definite (>95% likelihood), highly likely (75–95%), probable (50–74%), possible (25–49%) or unlikely (<25%).
A total of 200 subjects diagnosed with DILI were found in the registry. Of those, 41 had CLD and 159 had no evidence of CLD. So-called alternative medicine (SCAM) products were identified as the most common class of DILI agents. Approximately 59% of DILI in the CLD and 40% in non-CLD group were associated with SCAM use. Individuals with pre-existing CLD had similar severity including mortality. Twelve patients (6%) developed adverse outcomes related to DILI including seven (3.5%) deaths and five (2.5%) with liver failure. Mortality was 4.88% in CLD and 3.14% in non-CLD subjects over median periods of 58 (8-106) days and 22 (1-65) days, respectively.
The authors concluded that, in this liver disease registry, the causes, clinical presentation, and outcomes of DILI in subjects with CLD and without CLD patients were not different. Further study is required to confirm our findings.
Consumers often prefer SCAM to conventional medicine because SCAM is viewed as gentle and safe. The notions are that they
- are natural and therefore harmless;
- have been in use for ages and thus have stood the test of time.
Readers of this blog will appreciate that both notions are, in fact, fallacies:
- appeal to nature;
- appeal to tradition.
This new paper is an impressive reminder that SCAM’s reputation as a safe option is not justified, and that SCAM relies more on fallacies than on facts.
Brillia for Children is probably the most amazing homeopathic quackery I have ever encountered:
Uses: Enhance clarity, improve concentration of attention, reduce feelings of anxiety & stress, excitability, irritability and hyperactivity to improve attention, focus and mood regulation.
Active Ingredient: Lapine S-100 immune globulin mixture of homeopathic dilutions 12C, 30C and 50C.
Brillia is a unique combination of antibody science and homeopathic formulation. The active ingredient of Brillia is antibodies to the brain-specific S100 protein (S100B). This protein is an important regulator of many different intracellular and extracellular brain processes, e.g. various enzymes activities, calcium homeostasis, communication between neurons, etc. Since almost all mental and neurological diseases as well as temporal stress-induced conditions are accompanied by disturbance of the above-mentioned processes, especially communication between neurons, the normalization of these processes is considered to be a prospective way to treat people with such undesirable conditions. Brillia is an antibody conjugated to the S100B protein and does not alter the concentration of the S100B protein in the bloodstream. Brillia’s efficacy stems from its ability to regulate the activity of the S100B protein and does not alter its concentration. In order for a protein to have an effect in the body, it needs to bind to its target, such as an enzyme. Proteins have very specific conformations that ensure that only the correct protein binds to the correct target molecule. Once the protein correctly orients itself into the active site of the target molecule, this is when the protein causes an effect in the body. When Brillia binds to the S100B protein, the overall shape of the protein is altered, hindering its ability to bind to its target molecule and thereby controlling its activity in the body. In short, Brillia stops the S100B protein from acting in the body by changing its shape, consequently regulating levels of anxiety and hyperactivity.
PARENT TOOL | WATCH: DISCOVER BRILLIA
WATCH: WHY & HOW BRILLIA WORKS
Inactive Ingredients: Lactose monohydrate, magnesium stearate, microcrystalline cellulose. Does not contain artificial colors or artificial flavors.
Food Allergy Warning: This product contains lactose. Brillia is gluten free and nut free.
About active ingredients, the website tells us this:
Let’s start off with the active ingredient, registered with the FDA as Lapine S-100B immune globulin. Now we know this name can be intimidating, so we are going to break it down for you. Working backwards, “immune globulin” is just the “sciency” way of saying “antibody”, and don’t worry, we will get into what an antibody actually is in just a second. Next, “S-100B” is the name of the protein the antibody is designed to recognize in the body. Lastly, “Lapine” is just a descriptor of the origin of the antibody, just like the millions of other antibodies used each and every day in laboratories all across the world.
So, what exactly is an antibody? Antibodies are a naturally occurring protein and component of our immune system that are individually programmed to target a very specific protein, in the case of Brillia, the S-100B protein. It is important to understand that antibodies are one of the most specific and targeted molecules in our bodies, resulting in zero off-target effects — meaning that antibodies specifically look for and attach to their target only. This is why Brillia has no harmful side effects, because it only interacts with the S-100B protein. Not only does Brillia have absolutely zero side effects, it also has no contraindications with any other medications or supplements your child may be taking. This is due to Brillia’s extremely high level of target specificity, meaning that Brillia is so well targeted to the S-100B protein, it won’t even think about touching anything else in the body, including any other drugs or supplements.
Now that we know more about the active ingredient, let’s talk about its target, the S-100B protein.
The S-100B protein is a naturally occurring protein and is most prevalent in the brain. It is an important regulator of many processes such as regulating calcium levels and helping neurons communicate, but in our case, we care about how it influences the symptoms we mentioned earlier, such as anxiety and hyperactivity.
Given that S-100B protein influences these symptoms, it is quite intuitive that when the S-100B protein doesn’t do its job properly, these symptoms become more prevalent, and this is exactly what happens in those who suffer from anxiety, hyperactivity, stress and lack of focus.
So, what makes the S-100B protein, for a lack of a better term, mess up? The answer is quite simple, when the S-100B protein is overproduced or overactive, its activity becomes unnecessarily high, making it capable of causing these symptoms.
The firm even has something vaguely resembling evidence: a study that “shows that over the course of 12 weeks, Brillia had a significantly better effect on the severity of anxiety over those that did not take Brillia, therefore proving Brillia’s efficacy.” They show some actual results but the methods or source of the study are not disclosed. On Medline, I could not find it either. Therefore, I asked the firm to send it to me. This is the answer I got:
“Our studies were conducted in Europe and then published on our website. Please click here to view the full details found on our site.”
So, they have a study that they commissioned in Europe; it was done by researchers unnamed. The firm then put some data of it on their website. In other words:
- we don’t know who was responsible for the study;
- we cannot evaluate how rigorous it was;
- it has never been peer-reviewed;
- it is now being used for promotional purposes.
Personally, I don’t find this acceptable. In my view, this does not provide a legitimation to make far-reaching claims about the remedy. Until I have evidence to the contrary, I thus deem it safe to conclude that Brillia has no effect other than enriching the manufacturer.
The U.S. Food and Drug Administration issued warning letters to seven companies for illegally selling dietary supplements that claim to cure, treat, mitigate or prevent cardiovascular disease or related conditions, such as atherosclerosis, stroke or heart failure, in violation of the Federal Food, Drug, and Cosmetic Act (FD&C Act). The FDA is urging consumers not to use these or similar products because they have not been evaluated by the FDA to be safe or effective for their intended use and may be harmful.
The warning letters were issued to:
- Essential Elements (Scale Media Inc.);
- Calroy Health Sciences LLC;
- Iwi;
- BergaMet North America LLC;
- Healthy Trends Worldwide LLC (Golden After 50);
- Chambers’ Apothecary;
- Anabolic Laboratories, LLC.
“Given that cardiovascular disease is the leading cause of death in the U.S., it’s important that the FDA protect the public from products and companies that make unlawful claims to treat it. Dietary supplements that claim to cure, treat, mitigate or prevent cardiovascular disease and related conditions could potentially harm consumers who use these products instead of seeking safe and effective FDA-approved treatments from qualified health care providers,” said Cara Welch, Ph.D., director of the Office of Dietary Supplement Programs in the FDA’s Center for Food Safety and Applied Nutrition. “We encourage consumers to remain vigilant when shopping online or in stores to avoid purchasing products that could put their health at risk.”
Under the FD&C Act, products intended to diagnose, cure, treat, mitigate or prevent disease are drugs and are subject to the requirements that apply to drugs, even if they are labeled as dietary supplements. Unlike drugs approved by the FDA, the agency has not evaluated whether the unapproved products subject to the warning letters announced today are effective for their intended use, what the proper dosage might be, how they could interact with FDA-approved drugs or other substances, or whether they have dangerous side effects or other safety concerns.
The FDA advises consumers to talk to their doctor, pharmacist or other health care provider before deciding to purchase or use any dietary supplement or drug. Some supplements might interact with medicines or other supplements. Health care providers will work with patients to determine which treatment is the best option for their condition.
If a consumer thinks that a product might have caused a reaction or an illness, they should immediately stop using the product and contact their health care provider. The FDA encourages health care providers and consumers to report any adverse reactions associated with FDA-regulated products to the agency using MedWatch or the Safety Reporting Portal.
The FDA has requested responses from the companies within 15 working days stating how they will address the issues described in the warning letters or provide their reasoning and supporting information as to why they think the products are not in violation of the law. Failure to correct violations promptly may result in legal action, including product seizure and/or injunction.
A review conducted in 2015 reported community pharmacists are willing to adopt a professional role in counselling consumers about the appropriate and safe use of so-called alternative medicine (SCAM) but faced multiple barriers in doing so. This current review aimed to update and extend these findings, by identifying studies published since 2015 that reported on pharmacists across any setting.
Eligible studies published between January 01, 2016, and December 31, 2021, were identified across 6 databases (PubMed, Scopus, Web of Science, EMBASE, ScienceDirect and MEDLINE). A grounded theory approach was used to thematically synthesize the data extracted.
A total of 64studies representing pharmacists across 30 countries were included for review. The study designs varied and included:
- cross-sectional surveys (n = 36),
- qualitative studies (n = 14),
- pseudo-patient studies (n = 3).
Eight studies reported on practice and/or bioethical responsibilities and 19 studies documented factors that would enable pharmacists to fulfill these responsibilities, while 37 studies reported on both.
The authors concluded that these findings indicate research about pharmacists’ responsibilities associated with SCAM is evolving from gap analysis towards research that is proactive in advocating for change in multiple areas. These findings can be used to inform a consensus discussion among pharmacists and key stakeholders regarding a set of professional responsibilities that would serve in the development of: a clearly defined role and associated practice standards, and competency requirements that inform educational learning objectives for inclusion in undergraduate, post-graduate and continuing professional pharmacy education.
I am puzzled why so many researchers in this specific area seem to avoid clearer language plainly stating the essential, simple, and undeniable facts. I am equally puzzled why so few pharmacists speak out.
It is obvious that community pharmacists are firstly healthcare professionals and only secondly shopkeepers. As such, they have important professional and ethical duties. Foremost, they are obliged to inform their customers responsibly – and responsible means telling them about the evidence for or against the SCAM product they are about to purchase. This duty also entails that pharmacists must inform themselves about the best current evidence. In turn, this means they must stop tolerating the current plethora of under- or post-graduate SCAM courses that are not evidence-based.
As we have discussed ad nauseam on this blog, none of this is actually happening (except in very few laudable cases)!
By and large, pharmacists continue to go along with the double standards of a) evidence for conventional drugs and b) fairy tales for SCAM. In the interest of progress, patient safety, and public health, it is time that pharmacists wake up and remind themselves that they are not commercially orientated shopkeepers but ethical healthcare professionals.
Camilla spent ten days at the end of October in a sophisticated meditation and fitness center in southern India. Life has recently been hectic for the Queen Consort: at 75, she has been in a non-stop succession of various ceremonies for the funeral of Elizabeth II, always one step behind her husband, not to mention her new status as sovereign… Enough to block her chakras in no time.
She came to the resort with her bodyguards and a handful of friends and was able to take advantage of the tailor-made treatments concocted for her by the master of the house, Dr Issac Mathai, who created this high-end holistic centre on a dozen hectares of scented gardens near Bangalore. The program includes massages, herbal steam baths, yoga, naturopathy, homeopathy, meditation, and Ayurvedic treatments to “cleanse, de-stress, soothe and revitalize the mind, body and soul”, as the establishment’s website states.
Guests are required to follow an individualized, meat-free diet, with organic food from the resort’s vegetable gardens, based on lots of salads or soups – Camilla is said to be a fan of sweet corn soup with spinach. Cigarettes and mobile phones are not allowed, although it is assumed that Camilla must have some privileges due to her status… and the basic rate for the suites, which starts at $950 a night – the price of the rooms varies between $260 and $760, the rate including a consultation with the doctors.
Charles and Camilla have been fans of the Soukya Centre in India for a decade. The place corresponds in every way to their deep-rooted convictions about health. Like her husband, Camilla is a follower of organic food, she also practices yoga and treats her face with creams made from nettle and bee venom. For his part, Charles has long been an advocate of alternative medicine, homeopathy, acupuncture, aromatherapy, and also hypnosis… He even set up a foundation to support complementary medicine by lobbying the British health service to include it in complementary therapies for certain patients, which caused an uproar among the pundits of traditional medicine.
________________________
If you suspected I was (yet again) sarcastic about the royal couple, you are mistaken. The text above is only my (slightly shortened) translation of an article published in the French magazine LE POINT (even the title is theirs). I found the article amusing and interesting; so, I looked up the Indian health center. Here are some of the things I found:
The 1st impression is that they are not shy about promotion calling themselves THE WORLD’S BEST AYURVEDA TREATMENT CENTER. The doctor in charge was once a ‘Consultant Physician’ at the Hale Clinic in London, where he treated a number of high-profile people. As his professional background, he offers this:
M.D. (Homeopathy); Hahnemann Post-Graduate Institute of Homeopathy, London M.R.C.H, London; Chinese Pulse Diagnosis and Acupuncture, WHO Institute of Traditional Chinese Medicine, Nanjing, China; Trained (Mind-Body Medicine Programme) at Harvard Medical School, USA
The approach of the center is described as follows:
The fundamental principle underlying Holistic Treatment is that the natural defense and immune system of an individual when strengthened, has the potential to heal and prevent diseases. In the age of super-specialisation where human beings are often viewed as a conglomeration of organs, it is crucial to understand ourselves as multi-dimensional beings with a body, mind and spirit. These interconnected dimensions need to be in perfect harmony to ensure real well-being.
And about homeopathy, they claim this:
Homeopathy originated in 1796 in Germany, and was discovered by Dr. Samuel Hahnemann, a German scientist. Homeopathy is popular today as a non-intrusive, holistic system of medicine. Instead of different medicines for different parts of the body, one single constitutional remedy is prescribed. As a system of medicine, Homeopathy is highly scientific, safe, logical and an extremely effective method of healing. For over 200 years people have used Homeopathy to maintain their good health, and also to treat and cure a wide range of illnesses like allergies, metabolic disorders, atopic dermatitis, Rheumatoid arthritis, Auto-immune disorders.
At this stage, I felt I had seen enough. Yes, you are right, we did not learn a lot from this little exploration. No, hold on! We did learn that homeopathy is highly scientific, safe, logical, and extremely effective!
The question, however, is should we believe it?
The global interest in dieting has increased, and many people have become obsessed with certain fad diets, assuming they are magic bullets for their problems. A fad diet is a popular dietary pattern known to be a quick fix. This review article explores the current evidence related to the health impacts of (amongst others) detox diets (DDs). DDs are interventional diets specifically designed for toxins elimination, health promotion, and weight management. They involve multiple approaches, including total calorie restriction, dietary modification, or juice fasts, and often the use of additional minerals, vitamins, diuretics, laxatives, or ‘cleansing foods’. Some of the many DDs used today are listed below:
| Diet type | Duration | Foods allowed | Proposed claims |
| Liver cleansing diet | 8 weeks | Plant-based, dairy-free, low-fat, high-fiber, unprocessed foods are allowed. Epsom salt and liver tonics are also consumed. | Improved energy levels and liver function Toxins removal Improved immune response Efficient metabolism of fats and better weight control |
| Lemon detox diet/Master cleanser | 10 days | A liquid-only diet based on purified water, lemon juice, tree syrup, and cayenne pepper. A mild laxative herbal tea and sea salt water is also incorporated. | Toxins removal Shiny hair, glowing skin, and strong nails Weight loss |
| The clean cleanse | 21 days | Breakfast and dinner comprise probiotic capsules, cleanse supplements and cleanse shakes. A solid meal in lunch while avoiding gluten, dairy, corn, soy, pork, beef, refined sugars, some fruits, and vegetables. | Toxins removal Improved energy, digestion, sleep, and mental health Reduction in joint pains, headaches, constipation, and bloating |
| Martha’s vineyard detox diet | 21 days | Herbal teas, vegetable soups and juices, specially formulated tablets, powders and digestive enzymes are on the menu. | Weight loss Toxins removal Improved energy levels |
| Weekend wonder detox | 48 h | Protein-rich meals salads, detox-promoting superfoods, and beverages. Healthy lifestyle, spa treatments, and herbal remedies. | Toxins removal Improved organ function Strengthen body Enhance beauty |
| Fat flush | 2 weeks | Large meals are replaced with dilute cranberries, hot water with lemon, pre-prepared cocktails, supplements, and small meals | Toxins removal Reduced stress Weight loss Improved liver function |
| Blueprint cleanse | 3 days | Consumption of six pre-prepared vegetable and fruit juices is allowed per day. | Toxins removal |
| The Hubbard purification rundown | Several weeks | Niacin doses along with sustained consumption of vitamin-A, B, C, D, and E. Daily exercise with balanced meals. Restriction of alcohol and drugs. Sitting in a sauna for ≤ 5 h each day. | Toxins removal from fat stores Improved memory and intelligence quotient Better blood pressure and cholesterol levels |
Currently, there is no good clinical evidence for the effectiveness of DDs and some evidence to suggest they might do harm. Many of the DD are liquid-based, low-calorie, and nutrient-poor. For example, a part of BluePrint Cleanse, Excavation Cleanse, provides only 19 g protein and 860 kcal/day which is far below the actual requirement. Food and Agriculture Organization (FAO) recommends a minimum of 0.83 g/kg body weight of high-quality protein and 1,680 kcal/day for an adult. DDs may also induce stress, raise cortisol levels, and increase appetite, resulting in binge eating and weight gain.
As no convincing positive evidence exists for DDs and detox products, their use needs to be discouraged by health professionals. Moreover, regulatory review and adequate safety monitoring should be considered.
